I have a WR1 wireless thermostat, it's fine but doesn't control the timing. The central heating has a programmable timer, it's fine but doesn't control the temperature. These are in different places.
I want the house to not freeze while we're on holiday, and to warm up before we return. It seems the obvious way would be to replace the thermostat with something programmable. Is there such a thing which is compatible with the receiver? I don't want remote controlled internet stuff.
Cheers
